Shifting value is grouped to perform a pair wave beam associated with the cell ID detected, and the combination of the measurement result of wave beam will be existed
For the further refinement of time/frequency bias estimation in same group.For example, when UE can be by estimated in group
Sequence/frequency offseting value carries out average, incoherently multiple wave beams in combination group detection measurements, and/or to being estimated in group
The time/frequency deviant of meter takes weighted average (wherein, weight is based on RSRP, SINR, RSRQ or RSS measurement result) to enter one
Step refinement time and frequency (for example, sequential/frequency) bias estimation.Alternatively, UE can be based on the channel estimation for wave beam
Come the measurement result of multiple wave beams being coherently combined in group, and the time/frequency deviant through refinement is obtained, this is by examining
Consider multiple measurement results and carry out optimizing detection measurement.
